Equipment: 6SE + 2x barlow + ZWO ASI224MC. Captured using Firecapture. 12 frames, spaced 5 minutes apart, each corresponding to top ~10% of ~18,000 frames. Processed using AstroSurface. I aligned, rotated, and merged the frames automatically using a custom script I wrote in Python.

It so cool that when you watched that happen, it had actually happened about 33 minutes before that. That's how far away Jupiter is.... It took 33 mins for the light of that happening to hit your eye.

I love perspectives like that!!

Cool. Were you able to figure out which moon that was?
skylardarkfox
Probably Ganymede, based on distance, size and color.
JosephFarah
thanks guys! that's a great guess :) this is actually Io! Ganymede is quite a bit bigger, but the 4 Galilean moons look very similar at this angular resolution.
skylardarkfox
Huh. That makes sense. The size did throw me off, I suppose. I actually tried to sus this out by running time back with Celestia, but it wasn't rendering an eclipse shadow that I could definitively identify.

Cool, thanks for sharing

This is seriously impressive work. And I can appreciate the python scripting a lot!
JosephFarah
thanks so much!! I have more details about the scripting in another post I did on Jupiter's moons: /gallery/v6hJv6u
